Welcome, Chan. A 2002 is a great choice as a daily driver, but it must be well sorted. When I purchased my 02 a few years ago, the woman I bought it from drove it around 80 miles round trip everyday. It was in decent shape but needed many things because it was 30 years old.
The first thing is the engine bay. Carburated 02s are easy to work on and you dont need to be a hardcore mechanic to perform basic duties like oil changes, spark plugs or brakes. If the car has points and a condenser in the distribitor, replace them with an electric ignition upgrade. Have your carb tuned by some one who knows what they are doing. I cant tell you how many times my car wouldnt start because I screwed with the carb. Get a mechanic to look at the engine if you dont know what to look for. The M10 engine is bullet proof if taken care of correctly. Adjust the valves every 12,000 miles and keep up with the oil changes and she should run for years. My 76 02 still has the original motor (I think its never been rebuilt). Yeah it burns some oil and smokes every now and then. But it starts up every time I take her for a spin. I drive her to work about 4 times a week.
Here is a list of all the things I did to my 02 when I purchased it. Hope this helps!
Replaced ignition points and condenser with Pertronix electronic ignition
Changed the oil
Changed the spark plugs
Replaced the stock air cleaner with a K&N air filter
Checked the brake calipers for leaks or sticking or frozen brake pistons
Check the suspension bushings for cracks, wear. Also the ball joints
Checked the fluid level in the transmission and rearend differential
Checked the engine and transmission mounts
Checked all the fuses
Check to see if all the instruments are in working order
Make sure the wipers, turnsignals and high beams are working correctly
Checked the blower fan, heat and cold settings
Checked the heater valve to see if was leaking. This is the valve under the hood, on the passenger side, below the windsheid. It adjusts the hot and cold setting on your windsheild defroster. It can leak and, from what Ive heard, is a bitch to change out.
Checked the axle boots for wear
Checked the Guibo or Flex disk. Its a rubber "donut" that attaches the driveshaft to the transmission output shaft.
Checked the center driveshaft bearing
Drained the old coolant and put in fresh coolant
I recently replaced most of my coolant hoses with new ones. Cheap insurance.
Changed the fuel filter. Always carry an extra filter in your trunk with some extra fuel line and clamps.
Changed all the rubber fuel hoses under the hood. Most of them were cracking!
Got a fire extinguisher in my trunk. Please do this!
Ok, I think Im done. I should tell you that I checked most of this stuff after I purchased the car and it was sitting in my driveway. I bought the car for $1500 so I wasnt looking for a prestine example. Just a little project that would keep me happy and keep my wallet empty. Good Luck!
